Population density

The ratio between the annual average population and the land area. The land area concept (excluding inland waters) should be used wherever available; if not available then the total area, including inland waters (area of lakes and rivers) is used,

本指标为年平均人口与陆地面积（land area）的比值。应优先采用不含内陆水域（inland waters）的陆地面积统计口径；若无法获取该口径下的数据，则使用包含内陆水域（即湖泊与河流面积）的总面积。
